Abstract

A method of depositing pyrolytic carbon, which adheres well to a graphite support and is gas-tight, was developed and the physical properties of the deposit were evaluated. The fluidized bed technique was used in applying this method of coating to fissile granules of uranium oxide and uranium carbide. After explaining the conditions for coating the granules, the authors examined their macrostructure, microstructure and permeability. Their behaviour at high temperature was investigated with a view to using them in a reactor. (author) [French] Une methode de deposition de carbone pyrolydque adherant bien au graphite support et etanche aux gaz a ete mise au point. Les proprietes physiques du depot ont ete evaluees. Cette methode de revetement a ete transposee a des granules fissiles d'oxyde et de carbure d'uranium en utilisant la technique du lit fluidise. Apres avoir precise les conditions de revetement de ces granules, on etudie leur macrostructure, leur microstructure, ainsi que leur permeabilite. Le comportement de ces granules a haute temperature a ete examine en vue de leur utilisation eventuelle dans un reacteur.

(author) [Spanish] Los autores han elaborado un metodo para depositar carbono pirolitico que se adhiere fuertemente al soporte de grafito y es estanco a los gases. Han determinado las propiedades de dicho deposito. Este metodo de revestimiento fue aplicado a granulos fisionables de oxido y de carburo de uranio, utilizando la tecnica del lecho fluidificado. Despues de determinar las condiciones en que se efectua el revestimiento de esos granulos, los autores estudiaron su macroestructura y su microestructura, asi como su permeabilidad. Examinaron tambien su comportamiento a temperatura elevada, con miras a utilizarlos oportunamente en los reactores.
